literally means "the form that is shown"; it is the outward, physical
appearance of a particular trait

Mendel's pea plants exhibited the following phenotypes:

round or wrinkled seed phenotype

yellow or green seed phenotype

red or white flower phenotype

tall or dwarf plant phenotype

2. What is seen in the F1 generation? We always see only one
of the two parental phenotypes in this generation. But the F1
possesses the information needed to produce both parental phenotypes in the
following generation. The phenotype of the F1 is dominant to the
trait that disappears in the F1.

3. The F2 generation always produced a 3:1 ratio where the
dominant trait is present three times as often as the recessive trait.
